From the description of the score in control class above, it could be seen the lowest and the highest score of 25 students in the control class. The lowest
score in the pre-test was 40 and the highest score was 75 with an average of 58.64. After the writer gave the student material about recount text, the writer gave the
students post-test. The data showed in the post-test is the lowest score was 45 and the highest score was 85. And the average of the post-test is 66. It can be seen that
the control class could only gained score about 6.4 points.

Based on the table 4.2 above figured that from 25 students in the experimental class, the lowest score in the pre-test was 30 and the highest score
was 75 with the average 55.6. After the treatment using Two Stay Two Stray technique, the writer gave the students post-test. The data showed in the post-test
is the lowest score was 50 and the highest score was 90. And the average of the post-test is 68.4. It can be seen that the control class could only gained score about
